ldconfig: /usr/lib/wsl/lib/libcuda.so.1 is not a symbolic link about wsl HOT 6 OPEN

@seudonam you might want to take this issue with Team Green because those libraries are part of the Nvidia driver and not WSL.

The soname is the same and ldconfig complains:

root@texas:~# objdump -p /usr/lib/wsl/lib/libcuda.so | grep -i soname
  SONAME               libcuda.so.1

not a symbolic link is a harmless warning. And with Nvidia's developers immersed in AI and the stock going up-and-up I doubt they'll care about this issue!

ummm, my question is i am installing a flash wsl system, why this stupid warning coming up?

from wsl.

This problem still bugs me. I did a hard research from pytorch/pytorch#73487 to here.
Is this a WSL2 problem or Nvidia problem?

解决/sbin/ldconfig.real: /usr/lib/wsl/lib/libcuda.so.1 is not a symbolic link的问题
意思是说 /usr/lib/wsl/lib/libcuda.so.1 不是一个符号链接
它们的关系应该是：
libcuda.so -> libcuda.so.1 -> libcuda.so.1.1
那么，到/usr/lib/wsl/lib 目录
用命令
sudo mkdir backup #用超级用户，建立backup目录
sudo mv libcuda.so ./backup
sudo mv libcuda.so.1 ./backup
sudo ln -s libcuda.so.1.1 libcuda.so.1 # 建立超链接 libcuda.so.1 -> libcuda.so.1.1
sudo ln -s libcuda.so.1 libcuda.so # 建立超链接 libcuda.so -> libcuda.so.1

I agree with @dqsh06. The issue is mentioned at https://forums.developer.nvidia.com/t/wsl2-libcuda-so-and-libcuda-so-1-should-be-symlink/236301, and a fix, too.

cd /usr/lib/wsl/lib
sudo rm libcuda.so libcuda.so.1
sudo ln -s libcuda.so.1.1 libcuda.so.1
sudo ln -s libcuda.so.1 libcuda.so
sudo /sbin/ldconfig
